## GST, HST, PST, RST, and QST in Canada

The federal **GST (5%)** applies everywhere, but what happens after that depends on the province:

- Alberta, NWT, Nunavut, and Yukon charge GST only
- BC, Manitoba, and Saskatchewan add PST/RST on top of the pre-tax price
- Ontario and the Atlantic provinces use a single harmonized HST instead of separate lines
- Quebec applies GST + QST, and QST gets calculated on the GST-inclusive amount rather than the base price

## Frequently Asked Questions

### How do I calculate GST for my province?
Pick your **province or territory** from the dropdown and the calculator takes it from there, applying federal GST, harmonized HST, or GST plus PST/RST/QST using 2026 standard retail rates for that jurisdiction.

### What is the GST rate in Ontario?
Ontario runs on **13% HST**, a harmonized blend of federal and provincial tax. Select Ontario in the dropdown and you'll see a single HST line rather than separate GST and PST amounts.

### How is Quebec QST calculated?
Quebec charges **5% GST** on the pre-tax price first, then layers **9.975% QST** on top of the GST-inclusive amount. That's the standard compound method this calculator uses, not a flat 14.975% applied to the base price.

### What is the difference between GST and HST?
**GST** is the federal 5% tax that applies everywhere. **HST** folds federal and provincial portions into a single harmonized rate, somewhere between 13% and 15% depending on the province, so HST provinces never show a separate PST line.

### Does Alberta have PST?
Nope, Alberta sticks with **5% GST only** and skips provincial sales tax entirely. Select Alberta and you'll only see the federal GST applied to your amount.

### Is this Canada GST calculator official for CRA filing?
No, it's meant for shopping, invoicing estimates, and general learning. File your actual returns through the CRA and the relevant provincial system. Our [GST calculator guide](https://shoutingnow.com/blog/gst-calculator-guide/) links out to every country tool if you need more.
